Windshield wipers not working properly on 1999 Oldsmobile Intrigue

When I turn on the wipers the passenger side does not work at all but the driver's side will attempt to raise but only comes up about an inch. Is the problem the windshield wipers arms or the motor itself?

the nuts that hold the arms to the wiper linkage may be loose. with the wipers off, set the arms in park position and tighten the nuts. this usually happens when they are turned on while stuck like snow or ice.
